BOTTOM-PLATE FOR DRAIN-TILES.

Specification of Letters Patent No. 29,516, dated August 7, 1860.

T 0 all whom it may con cern:

Be it known that I, JOHN PARSONS, of Cleveland, in the county ofCuyahoga. and State of Ohio, have invented a new and useful improvementin the construction of hottoms for laying drain tiles upon to keep thedrain in a line, admit water freely, and to keep out sand, dirt, &c.,from which the drains would otherwise choke and be rens dered useless;and I do hereby declare the following is a true and exact description ofthe construction and operation of the same, reference being had to theannexed drawing, making a part of this specification, in which Figure Ais the bottom referred to, showing two ridges a, a. Fig. B shows thedrain tiles placed on the bottoms A, the ridges a, a, being inside ofthe drain tiles, keep the drain in a. straight line, and prevent thedanger of their being moved when filling in the dirt, it is necessary inlaying the drain tiles on the bottoms to break joints with the joints onthe bottoms.

The advantages of this improvement, that open or horseshoe drain tilescan be used with greater results than the close bottom drain tiles,inasmuch as water can have free inlet the whole length of the drain aswell as at the ends Without the danger of sand, dirt, or other matterbeing washed in over the ridges, and as a matter of saving, many tilescan be used that are not quite even at the bottom, and are now thrownaway occa sio-ning considerable loss.

I do not claim a bottom without the ridges as my invention, neither do Iconfine myself to the bottoms and ridges being made of any particularmaterial.

What I claim as my invention as an improvement, is

The two ridges a, a, on the bottom A, substantially as described,and-for the purposes set forth.

JOHN PARSONS.
